IMPROVEMENT IN HARVESTERS.

T0 -ALL WHOM IT MAY CONCERN:

Be it known that I, GEORGE M. JACKSON, of North Hector, Schuyler county, State of New York, have invented new and useful Improvements in Harvesters; and I do hereby declaro the following to be an exact description thereof, referencebeing had to the accompanying drawings, and to the lettersof reference marked thereon, making a part of this specification, in which- Figure 1 represents a. top view of the harvester. -Figure 2, a sectional view of the same.

Figure 3, the positions of the adjustable cutter-har frame. A

,The nature of my invention consists in the arrangement and combination of the 4toothed wheels, crank-box of the hingee frame, finger-bar, and hoisting-chain, with its lever for regulating thenpright or angular position of` the finger-bar frame, so that the nger-bar can be hcld up in a vertical position as the machine, approaches a tree, or in turning around, or at any angular position to suit the character of the ground, or at a downward position to'out the Vgrass from a. steep slope of the side of a hill, whilst the machine is allhtllc while in operation; avoiding the necessity of stopping the machine to shift or unshiift,thegearing-devices, thus shving much time and labor, and allowing the machine to be light and simple in construction, so as to be drawn by only A represents the frame, to which the `axle and carriage-wheels B are attached. C, the drivers seat.,

located at the rear e'nd of a hinged or pivoted and adjustable platform, D, to which the tongue or shaft E is attached. The front lever F is for the purpose of raising or lowering the frame in front, by means of the hook` Gr, and eye or clip H, to regulate the front of the frame, so that the.fingerbar J may move with the undulations of the surfa'celof the ground, or raised to escapestones or other slight obstructions. Springs K K are attached to the carriage-wheels B B, and wor/k in ratchets L L, on the axles, so as to hold the wheels, when the machine is in motion, and operate the driving toothed wheel M, that gears into the pinion N, that operates the shiftingbevel wheel O, that is shifted or unshifterl, when required, by means of the lever P. `The bevelwheel O gears into the pinion Q on the one end of shaft R. Qn the end of shaft R, in front, isA another toothed wheel, S, that gears into toothed wheel T, to which a crank, U, is attached, connecting with the end of finger-har J, and operates the cutter-bar. Extending down from the side of frame A, is a hinged frame, V, and support for the nger-har frame, and lto which the cutter-bar is firmly fastened, and `works `with the hinge or box W.

passing over a roller, Y, and`fastened to an upright lever, Z, by which means the-finger-bar frame is raised or lowered to the required angle or position, and the lever is held by the notched or ratchet end of the platform D.

The drivers seat being located in the centre, between the levers F, P, and Z, the driver, by a mere movement of his hand, controls either lever, and regulates the movement of the machine with perfect ease.

What I claim as my invention, and desire to secure by Letters Patent, is-

The arrangement and combination of the ,toothed'wheels S and T, crank U, box W, of the hinged frame V, adjustable finger-bar J, hoisting-rope or chain Y, and lever Z, when constructed and operated as herein described and for the purposes set forth.l
